New classes of mathematical objects have been uncovered in the last couple of decades, with names like Strange Attractors and Fractals. What they share is that they can only be revealed through computer-based mathematical operations called iterations and recursions. These can be conceptually difficult to distinguish; and this article is Brochmann's attempt at elucidating the difference. Recursive procedures 'call' themselves. HyperTalk and Pascal procedures that illustrate recursion.
